Abstract :
Summary form only given, as follows. The 100th anniversary of superconductivity will be celebrated during 2011. Therefore, a Special Session has been scheduled for IMS 2011 to highlight the potential impact of superconductivity on electronic technologies, especially in the microwave and terahertz frequencies regimes. In this paper, Part 1, the history, properties and some early high frequency applications of superconductivity will be reviewed, while in Part 2, current and future applications will be discussed.
